How are operating system updates distributed in the Oracle Solaris 11 environment?

How are operating system updates distributed in the Oracle Solaris 11 environment?

A.
Updates are only available to customers with an active support contract. The updates are
distributed through the My Oracle Support web portal and installed in a central location. All
software packages are then updated manually from the command line using the smpatch
command.

B.
Patches are download from http: //support.oracle.com either automatically or manually. All
software packages are then updated manually from the command line using the smpatch or
patchadd commands.

C.
Software updates are published as packages to a repository. All software packages are then
updated manually from the command line using the pkg command.

D.
Software updates, published as packages to an OS image. All software packages are then
updated manually from the command line using the pkg command.

Explanation:
* Updating all of the packages on your installed system To update all of the
packages on your system that have available updates, use the pkg update command, as follows:
# pkg update
Running this command updates packages that you might not otherwise consider updating, for
example, kernel components and other low-level system packages.
* Adding or updating individual packages To add individual software packages, use the pkg
install command. Any dependent packages are also updated at the same time.
* install package updates that deliver fixes A pkg update operation might include bug fixes, so the
operation is similar to applying a specific patch or patches in previous Oracle Solaris releases.
Note: The IPS interfaces first check for updates for currently installed packages before retrieving
them via the network. By default, interfaces check repository catalogs in the following locations:
* The default installation repository at pkg.oracle.com/solaris/release.
* The support repository in My Oracle Support. This repository is restricted to users with Oracle
Solaris 11 Express support contracts, and it contains packages with the latest bug fixes. For this
reason, a support contract must be purchased for production deployments.
